Geographical mapping of the specific disorders is expected to provide valuable insights into clustering of the conditions, which points to possible environmental and genetical determinants. So far, mostly geographical maps of motor neuron diseases have been reported. By using record information from the Dutch nationwide Computer Registry of All Myopathies and Polyneuropathies (CRAMP) we aimed to generate geographical maps for eight disorders predominantly diagnosed in adults. We investigated the geographical distribution of newly diagnosed patients in the Netherlands from 2004 to 2011. The variables used were diagnosis, date of diagnosis, and the first two digits of the postal code for geographical location from CRAMP. The number of incident cases was divided by the total number of people populating the postal code area. Nationwide incidence maps were constructed for myotonic dystrophy, progressive (spinal) muscular atrophy, chronic inflammatory demyelinating polyneuropathy, facioscapulohumeral muscular dystrophy, inclusion body myositis, hereditary motor and sensory neuropathy, Pompe disease and oculopharyngeal muscular dystrophy. Considerable regional variation between disorders was observed, particularly for myotonic dystrophy and facioscapulohumeral muscular dystrophy. We provided the first neuromuscular atlas of the Netherlands with maps for eight disorders commonly seen in the neuromuscular practice. To address possible outliers due to low population numbers, Bayesian smoothing techniques should be considered in future research.</div></div>","PeriodicalId":101058,"journal":{"name":"Rare","volume":"3 ","pages":"Article 100059"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developmental and epileptic encephalopathy 60 (DEE60) is an autosomal recessive disorder caused by mutations in the Canopy FGF signaling regulator 3 (<em>CNPY3</em>) gene. Symptoms start in infancy and include developmental delay, seizures, and myoclonus, with EEGs showing hypsarrhythmia indicative of West syndrome. <em>CNPY3</em> is crucial for Toll-like receptor chaperoning and can potentially cause neuronal circuit imbalances. This report examines the first reported instance of DEE60 in Pakistan with a missense mutation in the <em>CNPY3</em> gene, aiming to advance the current literature on <em>CNPY3</em> and bring attention to a rare condition that currently only has symptomatic treatment. Only five cases have been reported globally.</div></div><div><h3>Methodology</h3><div>Informed consent was obtained from the patient’s parents for the publication of this study and patient confidentiality has been maintained such that no data in the submission can reveal the patient's identity.</div></div><div><h3>Case presentation</h3><div>A 5-month-old male, born of consanguineous parents, presented to the Aga Khan University Hospital with severe seizures, a history of global developmental delay and a family history of seizures. The patient had his first seizure at 3 months and was started on antiseizure medications. He was born full-term via caesarean section, requiring oxygen support postnatally due to delayed cry and cyanosis. He exhibited delayed developmental milestones, low interaction levels, unresponsiveness to loud sounds and no smiling since birth. Systemic examinations were normal, but MRI and EEG findings suggested West Syndrome, DEE, and inborn errors of metabolism (IEM). Whole exome sequencing (WES) revealed a homozygous likely pathogenic variant in the <em>CNPY3</em> gene (NM_006586.5) c.275 C>T (p.Ser92Leu, rs556172653), confirming DEE60. At follow-up, the patient experienced increased seizure frequency, intermittent fever, recurrent chest infections and decreased muscle tone. Management included anti-seizure medications, benzodiazepines, anticonvulsants, neurobiotin, folic acid, vitamin B and ACTH. The parents were counselled about DEE60, prenatal testing, and a 25 % occurrence of recessive disorders. There is currently no gene therapy for this condition.</div></div><div><h3>Comment</h3><div>The variant reported in dataebases is predicted to be deleterious, consistent with the phenotype observed in our patient. ClinVar records 34 <em>CNPY3</em> variants with 20 variants of uncertain significance.
